IAPER FOLDING, CUTTING, AND DELIVERING MACHINE.

Application filed June 21, 1924.

lily present invention relates to an impi ovement in paper cutting and stacking ma chines, and more particularly to that type of machines in which a traveling web of paper is cut into predetermined lengths and each successive length of paper as cut from the web is placed in a stack of similar sections cut from the web, and furthermore to that form of apparatus in which each section of the web as cut therefrom may be transversely folded before the same is stacked. The apparatus is particularly adapted for use in the manufacture of paper napkins, towels, toilet paper and similar paper products. In the invention as illustrated, the paper web is preferably folded transversely before being cut and each section of the web as cut therefrom is folded in a position substantially midway its length and then delivered and stacked in a superimposed pile of similar sections of the web. The invention relates still more particularly to the means and the devices for actuating the same for transversely folding and positively gripping each section of the web and the delivery of the same to the stacking devices irrespective of the use to which the apparatus is applied, and also irrespective of the number of traveling webs which may be used at one and the same time and whether or not any or all of such traveling webs are folded transversely or not. A machine embodying my present invention will be hereinafter more particularly described.

Fig. 1:) is an elevation illustrating a modification.

As illustrated in the drawing the devices comprising my piesent invention are mounted in a suitable frame which may include uprights 20, 21, 22, a frame body 23, a transverse member 24, a frame side bracket 25, and oppositely disposed side plates 26 and 27 connected by a tie-bolt 28 or otherwise, it being understood that the other members forming the frame of the apparatus are also suitably connected so as to be secured to one another.

Journaled in bearings provided therefor in the plates 26 and 27, is a drive shaft 29. This drive shaft 29 is suitably coupled to a motor 30 mounted on a motor base 31, and secured in a suitable position preferably above the side plates 26 and 27 there is a starting box and controller 32 for operating the motor. Secured on the drive shaft 29 there is a pinion 33. This pinion 33 meshes with a gear 34 fixed on a shaft 35 suitably journaled in the side plates 26 and 27. Also secured on the shaft 35 is a pinion 36 which meshes with a gear 37 mounted on a shaft 38 also suitably journaled in bearings provided for this purpose in the side plates 26 and 27. The gear 37 meshes with a gear 39 which is fixed on a shaft 40 journaled in bearings provided for this purpose in the side plates 26 and 27. Also meshing with the gear 37 is a gear 41 which is secured to a shaft 42 also journaled in bearings provided therefor in the side plates 26 and 27. This train of gears is preferably mounted on one side of the side plate 26 as clearly illustrated in Figs. 1 to 4 of the drawing. The gears are so arranged that the gear 37 is driven at a speed considerably lower than the motor speed, although the speed at which the gear 37 is driven may be any speed necessary for the proper operation of the machine. The gear 39 is similar to the gear 37 so that the shaft turns at the same rate as the shaft 38 whereas the relationship between the gears 37 and ll is such that the shaft 42 turns at twice the speed of the shaft 38. The same relationship maintains between the gear 87 and the gear 36, that is to say the shaft 35 is geared to the shaft 38 so that the former turns at twice the speed of the latter.

Mounted on the shaft 35 between the side plates 26 and 27 there is a friction feed. roller 43. Mounted on the shaft between the side plates 26 and 27 there is a feed cylinder ll. Similarly mounted on the shaft ll) be tween the side plates 26 and 27 there is a feed cylinder 45. The friction feed or auxiliary feed roller 43 is preferably made of rubber or is provided with a rubber surface and in a suitable position in the surface of the same there is a transverse groove or notch 46. In the surface of the feed cylinder ll there are adjacently placed notches 4:7 and 41.8 extending across the surface of the same and in the feed cylinder l5 there is transversely placed a knife blade ll) and a pusher plate 50. llfoul'ited on the ends of the feed. cylinder 4-5.4. there are suitably spaced blocks 51 and 52, the purpose and function of which will be hereinafter oesoribed.

Also mounted between the side plates 26 and 27 there is a cylinder Tais is mounted on a shaft 5i journaled in recesses 55 provided therefor in the side plates and adjustably secured in position by nuts 56 or otherwise. Cooperating with this cylinder 53 is a roller 57 carried at the corres iondingg lower ends of levers 58 which are mounted at their upper ends in a shaft 59 fixed in the side plates :26 and if the roller 27 being normally maintained against the surface of the cylinder 53 by the weight thereof and that of the arms through the action of gravity.

Mounted on the shaft d2 between the side plates 26 and 2? there is a creaser cylinder 60. In the periphery of this creascr I indcr there are suitably spaced circumferential grooves 61 and 52. This creaser cylinder is also provided with a longitudinal groove 63. At the ends of this cylinder the same is pro- 'vided with recesses 64: and 65. Also mounted on the shaft 4-2 and between the ends of the cylinder in the adjacent inner faces of the side plates 26 and 27 there are rocker plates 66 and 67. These roclrer plates are suitably connected to hearing sleeves (i8 and 69 respectively which are journaled on the said shaft d2 so that these roclrer plates turn on the shaft. In the longitudinal groove 63 in the surface of the cylinder 90 there is a clamp or gripper bar 70. The opposite ends of this gripper bar shouldered as indicated at 71 and 72 respectively and the e2; treinities of the gripper bar extend into recesses 73 and 74 provided therefor in the rocker plates 66 and 67. At one end of the neaasar cylinder there is a pin 75, and in a similar position at the opposite end of the cylinder there is a pin 76. These pins at corresponding ends are suitably secured in the body of the cylinder. Both pins are adapted at their outer ends to lie in the recesses 64 and and are provided with springs 77 and 78 which extend from collars 79 and 80, against which corresponding ends of the springs are adapted to bear, to the said clamp bar so as to normally maintain one face of the clamp bar 70 in contact with the adjacent face defining; one side wall of the long" dinal. groove in the surface of the cylin der G0, thus will be understood maintaining the rocker plates 66 and 67 in a predetermined position relatively to the cylinder. As indicated particularly in Figs. 5 and 9. the adjacent normally abutting faces of the clamp bar 70 and the wall delining the recess 63 are provided with grooves 81 and 82. In the cylinder 44: in a position diametrically opposite that in which the notches l7 and 48 are placed there is a pusher bar 83 which cooperates with the grooves 81 and 82, as will be hereimifter more particularly described.

.i issociated with the feed cylinder rte; there are stripper rods 8% and 85. These stripper rods are suitably connected to collars 86 and 87 respectively both mounted on a shaft 88. These stripper rods at their free ends enter circumferential grooves 89 and 90 respectively provided in the feed roll ll for the purpose of directing the folded paper from the surface of the roll or cylinder, as will be hereinafter more particularly de scribed.

Associated with the creaser cylinder 60 is an auxiliary creaser cylinder 91. This cylinder 91 is mounted on stub shafts 92 and 93 connected respectively to brackets 94 and 95 which are secured in any suitable manner to the frame of the machine. Extending into these grooves 61 and 62 in the creascr roll 60 so that the extremities thereof lie between the creaser cylinder (90 and its auxiliary cylinder 91 there are stripper rods 98 and 99 which are carried by a plate 190, secured to the frame of the machine in any suitable manner.

From the foregoing it will be understood that the feed cylinders a l and 45 also act as cutter cylinders and that the creaser cylinders GO and 91 also act as delivery cylinders.

The devices for receiving and piling the folded sheets of paper comprising towels napkins or other articles into stacks of predetermined number may as illustrated include a shaft 101 mounted in bearings 102 and extending iransve .ily of the cylinder shafts as hereinbefore described and at one end of these cylinders and below the same. At the other end of the cylinders and in a similar position there is a corresponding transverse shaft 103 mounted in bearings 10% suitably secured to the frame of the machine. Both these shafts are driven from the shaft 4-2. On the shaft 12 there is a worm 105 and on the shaft 101 a worm gear 100. Similarly on the shaft 42 there is a worm 107 and on the shaft 103 a worm gear 108. The shafts 101 and 103 are driven in opposite directions and as viewed in Fig. '10, for example, the shaft 101 revolves in a clockwise direction and the shaft 103 in a countcrclockwise direction. These shafts extend an appreciable distance beyond the frame of the machine and carry devices for receiving the sheets of folded paper as the same are delivered by the machine.

On the shaft 101 there is a drum 109. Secured in the surface of this drum and extending longitudinally thereof there is a se ries of receiver blades 110. As illustrated the apparatus is designed to deliver 10 folded sheets with each revolution of the drum and for this reason there are 10 equally spaced receiver blades fixed longitudinally in the drum. Each of these blades divided into sections leaving spaces 111 and 112 in predetermined positions between the adjacent ends of the sections of each blade. At the inner end of each blade the same is bent or curved as indicated at 113 in a direction in advance of the direction in which the drum is adapted to revolve in order to in sure the entry of a folded sheet between adjacent support blades in the operation of the apparatus, as will also be hereinafter more particularly described. Similarly on the shaft 103 there is mounted a drum 10 1 in the periphery of which there is secured a corresponding series of support blades 115. Each of these blades 115 is composed of sections spaced at suitable intervals as indicated at 116 and 117, these spaces corresponding, of course, with the similar spaces in the complementary support blades of the drum 109. Also at their inner ends each of these support blades 115 is bent or curved in the direction corresponding to the direction in which the drum revolves, the curved ends of the blades 115 being designated at 118.

Adjacent the outer end of the drum 109 there is a disk 119 against which the adjacent ends of the support blades bear, and similarly at the outer end of the drum 11 1 there is a disk 120 contacting with the adjaeent ends of the support blades 115. On the shaft 101 there is a collar 121 and on the shaft 103 there is a similar collar 122. As will be understood, the disk 119 may be integral with the collar 121 and the disk 120 integral with the collar 122 or otherwise, and the disks serve as stops to limit the outward movement of the folded sheets as they are delivered from the delivery rolls or cylinders to the support blades 110 and 115 carried by the drums 109 and 11 1. The collar 121 is provided with a radially placed pin 123.

Support blocks 12 1 and 125 are suitably secured to the frame of the machine and cxtend beneath the drums 109 and 114. Coin nected to the support block 12 1 there are brackets 126. and similarly connected to the support block 125 there are'brackcts 127. In each bracket 126 there is fixed a vertical guide bar. As illustrated and inasmuch as there are two divisions in the support blades there are two brackets 126, in one of which one guide bar 128 is fixed and in the other of which a guide bar 129 is fixed. Similarly beneath the drum 109 there are two brackets 127. In one of these a guide bar 130 is fixed and in the other a guide bar 131 is fixed. The brackets 126 are so placed that the guide bar 128 extends upwardly and its upper extremity lies within the space 116 and the guide bar 129 extends upwardly with its extremity lying within the space 117. In the same manner the brackets 127 are so placed thatthe guide bar 130 extends upwardly and its upper extremity lies within the space 111 and the guide bar 131 extends upwardly and its extremity lies within the space 112. Ihe oppositely disposed guide bars, namely 128 and 130, and 129 and 131 are so spaced from each other as to be of approximately the same width as the folded strip of paper delivered from the machine to the support blades and from the support blades to the temporary support as hereinafter described.

Mounted in the brackets 127 and extending through the guide bars 130 and 131 a rocker shaft 132. Fixed in this rocker shaft is a series of support arms 133. These are suitably spaced and of any desired number and each at its end is preferably upturned as indicated at The rocker shaft 132 and the support arms carried thereby are normally maintained in position andv when moved returned to this position by a spring 135 surrounding a portion of the rocker shaft. Similarly in the other side of the machine there is a corresponding rocker shaft 136 which is mounted in the brackets 120 and extends through the guide bars 128 and 129. Fixed in this rocker shaft 136 there is a correspomling number of support arms 137 each of which at its outer end is upturned as indicated at 138. The rocker shaft 136 and the support arms carried thereby are normally n'iaintaincd in position and when moved returned thereto by a spring 139 surrounding a portion of this rocker shaft. At the inner end of the rocker shaft 132 there is a collar 140 carrying a crank arm 14:1 and al the inner end of the rocker shaft 136 time is a collar H2 tarrying a crank arm 1 13. The crank arm I-ll is connected to the crank arm 1413 by a link l-fet and as indicated these parts may be normally maintained in an initial position ably n'iounted stub shaft 141' titti d with a removable head it? and an in: huh i 33 and an outer hub 14's these pa being maintained in their relative po'--iiioiu: by means of a spring 150 or otheiwnie. "he inner huh hi8 is provided witn :1 series placed pins 151 and the outer huh a similarly placed series of pins; 1::2. pin 143 secured in the collar 121 hereinhefore described is adapted to contact with each of the pins in the outer huh 1&9 and in a suitable position in the. outer face to contact; with the pins 151 on the inner huh 14-8. At the outer end of the reel shalt .32 there is a trip lever 155, and on one of the wins 1553 there is a trip pin I io-t adapted to engage with the trip lever '3. its illus tinted the drums 109 and till are both provided with ten support blades so that 10 folded sheets or napkins or towels are delivered with each revolution of these drums. The inner hub 14-6 is provided with live radial pins 151 and the outer huh 14-9 with five radial. pins 152 so that when the pin 123 contacts with one of the pins the inner and outer hubs are moved tenth of a revolution and when the block 152-? contacts with one of the pins 151 the inner and outer hubs are moved another tenth of a revolution so that with each revolution of the drums 109 and 11% the inner and outer heads are moved a fifth of a revolution. The pin 154: contacts with the trip lever 155 once in each complete revolution of the inner and outer hubs and in so doin swings the rocker shafts and the support lms cairied thereby from the full line to the dotted line positions in Fig. 11 of the drawing to drop 50 of the folded sheets which are delivered to the upturned ends of the support arms with every live revolutions of the drums 109 and 114. It will be understood that this arrangement is only diagrammatic and that the apparatus may be readily changed to deliver any other ncdctcrmined number of folded sheets as may he desired.

ltn order in some instances to prevent one or more of the folded sheets from missing the support arms in the event of the support arms not returning to their initial positions in time to receive the next succeeding sheet after having delivered a stack of the sheets, it may be advisable to employ auxiliary support arms such, for example, as illustrated in Figs. 12, 13 and 14. To this end as shown in these figures of the drawing the drum 109 may be fitted with a rocker shaft 156 in which auxiliary support arms 157 are secured the rocker shaft and its support arms being yieldingly maintained in an initial position by the action of a spring 158. Similarly in the drum 114: there is a rocker shaft 159. This is fitted with auxiliary support arms 160 oppositely disposed to the auxiliary support arms 157. The rocker shaft 159 and its auxiliary support arms 160 are normally maintained in an initial position by the action of a spring 161. In this structure there is a front plate 162 extending between the shafts 101 and 103 and lying immediately behind the disks 168 and 164 which correspond to the disks 119 and 129. At the rear or inner side of the front plate 162 there are spacer plates 165 and 166. The rocker shaft 156 and its auxiliary support arms 157 are actuated through suitable crank arms and cams. As illustrated, for this purpose there is an outer cam 167 and an inner cam 168 while at the end of the rocker shaft 156 there is a hell crank 169 provided with suitable pins on which rollers 170 and 171 are mounted. These are clearly illustrated in Fig. 14 of the drawing. The rocker shaft 159 and its auxiliary support arms 160 are operated in the same manner by similar cams placed in the reverse positions. The outer cam for this purpose is indicated at 172 and the inner cam at 173. while the bell crank at the end of the rocker shaft 159 is indicated at 174 and the rollers for contacting with the faces of the cams are indicated at 175 and 176. The roller 170 is adapted to bear against the face of the cam 167 and the roller 171 against the face of the cam 168. Similarly the roller 175 is adapted to bear against the face of the cam 172 and the roller 17 6 against the face of the cam 173. The faces of these cams are so shaped that when the auxiliary support arms are in a juxtaposed position between the drums they are substantially horizontal and continue to assume substantially horizontal. position for a continued portion of the revolution of the drums. at the same time receding from each other so as to receive a folded strip of paper as the same is delivered from the machine and to support the same until the support arms 133 and 137 have returned to their initial position to perform the function of supporting these folded sheets of paper as the same come from the machine and are fed to and delivered by the support blades 110 and. 115, it being understood that when the rollers 170 and 175 run off the faces of the cams 167 and 172 the rollers 171 and 176 engage the faces of the cams 168 and 173 and in so doing shift the rocker shafts to such positions that the auxiliary support arms are out of the way of lltiil other operative parts of the mechanism. It will also be understood that these auxiliary support arms thus come into play to receive every tenth sheet of the folded web of paper, that is to say every tenth paper napkin, towel or similar article. As the articles piled in stacks of predetermined numbers are dropped by the support arms and 137 they are guided in their descent by the guide bars 128, 129, 130 and 131 and fall upon a platform 177 mounted beneath the same and supported by a bracket 178 suitably fixed in the frame of the machine. From this platform, as will he understood, each pile of superimposed sheets may be suitably removed and bundled.

As shown a traveling paper web is folded longitudinally into a predetermined number of sections as may be required by any suitable apparatus, such for example as shown and described in my copending application, Serial No. 682,450, filed December 2-1, 1923, for a paper folding machine. This paper folding machine comprises complementary members for longitudinally folding the paper, one of which is fixed and the other adjustable to position relatively thereto. As shown in the drawing the fixed member of this longitudinal folding; device as indicated at 179 may be secured in the frame of the machine by a bracket or other support 180 and the movable member 181 may be supported on slidable base 182 which when adjusted to the desired position may be fixed therein by a set screw 183 or otherwise. The paper to be folded is supplied from a reel indicated at 18 t and passes over a suitmounted idler 185 and over the rollers 186 forming part of the devices for longitudinally folding the web.

In order to prevent the paper from feeda 00 rapidly and also to prevent the momentum of the reel from feeding the paper r the machine is stopped and before the s started again example, it may be adii ihle in some instances to provide a poi' -vt feed for the paper as the same is unwound from the reel. To this'end the trunnions 187 of the reel are passed between the sides 188 of yoke members carried by 189 so that the ree 18% may rest n a cylinder 190 mounted on a shaft 191 journals-d in the brackets. The ends of the cylinder 190 are provided with flanges 199 between which the reel of paper passes so that the flanges assist in guiding); the paper as the same is unwound from the reel. The brackets 189 are conneced -y a tiebolt 193. The raft 191 and the cylinder 190 mounted thereon are positively driven from the shaft I553. Sn the shaft 191 there a gear 19% 1 fh' I with a ge on vertical shalt at the opposite end of the vertical shaft 196 there is a gear 197 meshing with a gear 198 on a shaft which is connected by a coupling 200 or otherwise to a shaft 201 suitably connected to the shaft 38, at the opposite end of which at the side of the machine there is a handle 202 by which when necessary when the power is disconnected ihe revolving parts 01 the apparatus may be turned over. It will be understood that the reel 184 will therefore be turned positively and the paper correspondingly fed therefrom although the speed at which the reel is turned is not sufficient to entirely feed the paper so that there is a predetermined decree of slip between the surface of the cylinder 190 in order of course that the paper as supplied to the folder is under the i'iecessary tension.

In the operation of the apparatus the paper web indicated at 203 is fed from the reel 18%: through the members 179 and 181 of the folder device, such for example as shown and described in my copending application Serial No. 682350, as aforesaid to fold the web longitudinally, that is in the direction in which it travels into a plurality of sectio The web thus folded as indicated at 0-l passes between the cylinder 53 and the roller 57 and then between the cylindcr and the feed roller 43, thence between the feed cylinder ll and the feed cylinder ll irh each revolution of the cylinders and the knife blade 49 enters the notch i and cat; a strip of predetermined length from the traveling web. The length of this st ip is approximately the circumference of the cylinder 44. After the web is thus cut the pusher or insertion plate engages the end of the advancing web and insures the sirip of material after passing between the t (ed cylinder ll and the deliverv cylinder (i0 freed from the surface of the feed cylinder it by the stripper rods 8-1 and 85.

the cylinders 44 and continue to revolve the projections 205 on the rocker plate; 6:; and ()7 come into contact with the UlilCnS and because of the fact that the surface speeds of cylinders 60 and 1% are the satire and projections 205 extend beyond the surface of cylinder 60 while blocks 52 stop short of the surface of cylinder alt), the revoluble motion of the rocker plates 66 and GT is retarded relatively to the cylinder 60 against the action of the he same being properly fed between the springs 77 and 78 and this action also retards the motion of the clamp bar causing an opening between the same and the taco defining the adjacent Wall of the groove tor the entrance oi the pusher or insertion bar 83 and the central portion of the strip of the Web. In the continued revolution of the cylinders n and 60 the edge of the pusher or insertion bar first coacts With the recess 82 and as will be understood as the cylinders continue to revolve the pusher or insertion bar is witl'idraivn from the groove and in doing so operates in the recess 81 and the projections 205 move oil ot the springs 77 return the clamp bar and the roclter i s to their initial positions whereby this "a transverse portion oi the section of web gripped between the clamp bar e adjacent Wall defining the recess 63. .tral portion oi the section of the is transversely gripped is carried by inued revolution of the cylinder (50 l he projections 206 on the rocker plates "1' d 6? come into contact with the blocks 51. Just prior to the time When the transve s ly folded edge of the section of the Web passes under the stripper rods 98 and 99 the extremities 206 of the roclrer plates (223 and (ST come inio contact with the blocks 51 and again retard the rcveluble motion of the rocker plates relatively to the delivery cylinder 30 and correspondingly retard the moven'ient of the clamp bar '70 against the actions of the spring 1"? and 78 to release the -tolthed edge of the section oi the paper Web to permit the sam to pass beneath the cuts of the stripper rods and between the delivery cylinder (50 and the auxiliary delivery cylinder 91.

Each transversely folded section of the Web is then passed by the delive y cylinder 00 and the auxiliary cylinder 91 between adjacent support blades .110 and on the revolving drun'is 109 and 111, each succeeding section of the paper Web being supported upon the lower set of support blades and delivered thereby to the upturned ends 13a and 138 oi the support arms and 13"? after having been suitably positioned by the guide bars 128, 129, and 131. it will be understood that the parts are timed in such a manner that the successive transversely folded sections of the Web as they come from the delivery cylinder and the auxiliary delivery cylinder pass between the succeedira j sets of support blades 110 and 1121 the inner ends of these support blades being turned in the direction of the rotation of the drums to which they are connected to lfacilitale and make this action certain. its the sections of folded web accumulate on the upturned ends 13st and 138 of the support arms the Weight of the same may depress the support arms against the actions or. the springs weasel and 139 and When a predetermined number of the transversely folded sections of the Web are delivered to the support arms the rocker shafts 132 and 136 are actuated through the tripper mechanism to permit a predete mined number of articles to fall to the platform, being directed thereto by the guide bars 128, 1:29 130 and 131. As illustrated, and as hereinbefore described there are ten sets of the support blades 110 and 115 so that ten articles are delivered with each revolution of the drums 109 and llet, and as the tripper mechanism is set to operate once in every live revolutions of the drums there Will be liil'ty transversely folded sections of the Web or articles piled in each staclr as the same are permitted to fall to the platform. As hereinbeliore stated, however, this number is only illustrative as the apparatus may be constructed and set to pile any predetermined number of the articles in each stack.

Also as hereinbettore described in some in stances it may be advisable to employ the au iliary support arms 15'? and which are operated by the cams and associated parts as hereinbefore described to bring the auxiliary support arms into operative posi' tion once in each revolution of the drums 109 and 114: so as to receive each tenth transversely tolded section 01' the 1111?) to sup- 137 are returned to their initial positions 1 when the folded sections of we vvcb are delivered by the auxiliary support arms 151" and 160 to the upturned ends 123% and Car of the main support arms and 131'. It will fintheinilore be understood that the :j perimposed piles of transversely 'tOltlt-(l sec tions of the Web comprising paper napkins towels or other articles 5 aclred in prcdetcr mined numbers hcreinhetorc describet may be suitably conveyed from the p. p to which they are delivered and wrapper anotiier mechanism or placed in a suit; container by de ices which form no pa (:1 my present invent-ion.

It is to be noted that the apparatus as herein shown and described is designed to transversely fold and stacl; paper napkins folded in a predetermined manner. that to say the Web from which the napi I made is first longitudinally folded and then predetermined sections ol' the Web cut there- L- where it is not necessary to fold the sections as cut from the web, as in toilet paper, the pusher bar may be placed between the notches 47 and 48 whereby the end of the traveling web whether folded or otherwise is forced into the grooves 81 and S2 and the sections of the web are successively fed endwise to the delivery cylinder. Obviously also this pusher bar may be placed at any desired angle instead of extending longitudinally across the cylinder 44.

As herein shown and described, particular reference being made to Figs. 5 and 6, it will be noted that the contact blocks 51 and are placed in a position within the circumference of the cylinder 44;, the radius of the same, therefore, being less than that of the cylinder while the projections 205 and 206 of the rocker plates extend beyond the surface of the delivery cylinder 60 and the length of the contact arms formed by these projections is therefore greater than the radius of the cylinder 60. As the peripheral speed of the cylinders 44 and 60 is the same the blocks, as hereinbefore described, retard the rocker links while the springs 77 and 7 8 tend to advance the same and to maintain them in an initially normal position. It will be apparent that these conditions may be reversed and the same results obtained, that is to say the blocks 51 and 52 may be extended beyond the periphery of the cylinder 44 so that the radius of the contact points is greater than the radius of the cylinder 44: and the projections 205 and 206 of the rocker plates may be shortened so as to lie within the periphery of the delivery cylinder 60 making the radius of the same less than that of the cylinder (30. This obviously will reverse the action hereinbefore described. but obviously will produce the same result. Other equal and obvious changes may be made in the apparatus to accommodate the same to various working conditions withoutdeparting t'rom the nature and spirit of my invention.

In some instances, particularly in cutting and stacking sections of a paper web which has been longitudinally folded to provide an outermost portion which is narrower than the folded web, and under certain atmospheric conditions the static electricity may be sufficient to cause these narrower sections f th articles to be displaced either moving outwardly or otherwise and to prevent the articles from nesting properly while being stacked. To overcome this difficulty I may employ a pneumatic device to maintain these narrower sections of the folded article in position while being stacked. As illustrated in 15 for this purpose I may employ a pipe 203 secured in the machine and projecting downwardly at a predetermined angle immediately above and between the drums 109 and 114 and the blades 110 and [15 carried thereby respectively. Along the bottom of this pipe 203 there is a series of spaced apertures 204; and by a blower or any other similar device. the draft of air is forced to and through the pipe, being admitted downwardly through the openings therein against the central portion of each of the sections of the web as it is delivered to the said blades in order, as hcreinbefore stated, to maintain the central portions of the folded sections of the web in position to assist in properly nesting the same while they are being stacked.
